Specification of Letter Patent.

' Patented Apr. 4, 1916.

Application filed December 22, 1913. Serial No. 808,068

' To all whom it may concern:

Be it known that I, LAFAYETTE Lnvmcs- TON, residing in the city andcounty of San Francisco, State of California, have invented certain newand useful Improvements in Bottle-stoppers, whereof the following is aspecification.

This invention relates to closures especially for milk bottles, and moreespecially to that class which consists in a more or less flexible diskthat engages a croze in the bottle and is thereby retained in place. Asis Well known these closures have to be re moved to get out the contentsof the bottle. This is done either by a tag stapled onto the disk whichtag necessitates the disk being applied with the tag side up; or else,in the case of a plain disk, a'tool is required. By my invention I avoidboth these objectionable features. This I do by incompletely cutting outa portion of the disk, which portion may be opened by a pressure of afinger or instrument, thus forming an opening or hatchway in the disk,through which the,

contents of the bottle may be discharged, or a finger inserted to raisethe move it completely.

In the accompanying one sheet of drawing I have illustrated my inventionby representing an embodiment of it in its best form.

In the drawings: Figure l, is a sectional elevation of a milk bottlewith my disk in place and the hatchway open after the.

closure has been pressed down. Fig. 2, is a perspective view of a diskwith the hatchway open. Fig. 3, is a plan of a disk withthe hatchwayclosed, and, Fig. 4, is ah section on the line 4-, i of Fig. 3. l 'l Inthese figures: 1 represents a milk bottle of the usual form, providedwith the usual croze 2, to engage andholcl a disk'3, said disk beingcommonly made of a heavy paper or card board. The disk 3 is providedwith a hatchway t of approximate square shape, formed by cutting throughthe material or nearly so along theline 5, 5. The cut does notcompletely encircle the hatchway, but leaves a portion of its peripheryor circumference intact to form holding means, as at 6, 6 whereby thehatch 7, is retained in place either in a closed. or opened position.

In practice I have found it convenient to make the cuts 5, 5 with aknife die, either before or after cutting out the disk, and

disk and re-.

then the device may be treated with paraiiin whereby the cuts 5, 5 aresealed and the disk made impervious and sterile.

When the disk is in place in the bottle, the hatchway remains closed. Toopen the same it suffices to presswith a finger or instrumentupon thehatch 7, at either of through one of the corners of the open hatchway,or a finger may be inserted and the whole disk lifted away from thebottle. Having thus described my invention and believing I have produceduseful and novel A improvements 1n the art to which it appertains,let-it be understood that I do not wish to be limited to the exactarrangement of the several parts composing the same as many changes canbe made without departing from the spirit thereof, but

What I claim and desire to secure by United States Letters Patent is:

1. A bottle closure comprising a disk provided with a central squarehatchway and a hatch closing the same formed by cutting through the diska portion of the sides of two opposite corners and the remainingintegral corners forming holding means to keep said hatch in position.

2. A bottle closurecomprising a disk provided with a hatchway' ofapproximate square shape, a hatch in said hatchway the hatch centrallyin an opened position within the hatchway.

In testimony that I claim the foregoing I have hereto set my hand in thepresence of witnesses, the 28th day of November, 1913.
